IMPROVEMENT IN PUMPS.

Specication forming part of Letters Patent No. 56.871, dated August 7, 1866.

. reference being had to the accompanying drawings, and to the letters of referenc-"marked thereon, in which- Figure l. represents a wooden pump-top, c, with a barrel attached, C, and a short piece of tubing, D. Fig. 2 represents theinner barrel, B B, and the packing-rings c a a. Fig. 3 rep resents the outside barrel, O C, the inside barrel1 B B, and the packing-rings a c a.

The nature of my invention consists in the` introduction of a glass, stone, or a metallic tube or barrel into the barrel of a wooden pump in such a manner as to admit of its being tightly 4packed and rinly held in its place by rubber or other elastic rings, thereby forin' in the usual manner, or form on the outside and then bore or ream it out larger than the inside barrel, so as to be able to put a packingring between the two barrels, as shown in Fig. 3, c c a. rIhe inside tube being formed of the proper size and length, the rubber rings are placed on it at their proper places,as shown in Fig. 2, c a, a, and it is then inserted into the wooden barrel, `as shown in Fig. 3.

The object of this arrangement is to obtain a barrel that shall be perfectly smooth, dura ble, and not liable to get out of order.

I am aware that pump-barrels have been lined but have not remained tight, owing to the contraction and expansion of the barrels; but with my elastic rings this diiiculty is fully obviated, not only in making them perfectly tight but in retaining thein in their proper place.

After thus fully describing the construction and operation of my invention, what I claim as new, and desire to secure by Letters Patent,`is

The inserting of a glass, stone, or metallic tube orlining into the barrel of a wooden pump, and firmly holding it there by means of rubber or other elastic rings, in the manner and for the purposeheretofore set forth.
